New Cambria Havergate quartz countertop just installed after breaking my Corian countertop in half using an air fryer (make sure you put a cutting board under your air fryer, even though the manual doesn't say to). I found tile I loved today to go with it, Dream Maya Bay Lapis 1 x 4 in. Glass Brick Tile. I am at a loss as to what color grout to use. I have two sections of backsplash in my kitchen, one is only 3 feet long, the other is 13 feet. The edging will be done in Schluter Systems satin copper bullnose.
Thoughts on grout color?
